Linkages between stratospheric ozone, UV radiation and climate change and their implications for terrestrial ecosystems
(Royal Society of Chemistry, 2019-06)
Exposure of plants and animals to ultraviolet-B radiation (UV-B; 280–315 nm) is modified by stratospheric ozone dynamics and climate change. Even though stabilisation and projected recovery of stratospheric ozone is expected ...
Solar UV radiation in a changing world: roles of cryosphere-land-water-atmosphere interfaces in global biogeochemical cycles
(Royal Society of Chemistry, 2019-01)
Global change influences biogeochemical cycles within and between environmental compartments (i.e., the cryosphere, terrestrial and aquatic ecosystems, and the atmosphere). A major effect of global change on carbon cycling ...
Field-grown soybean induces jasmonates and defensive compounds in response to thrips feeding and solar UV-B radiation
(Pergamon-Elsevier Science Ltd, 2018-12)
Solar UV-B radiation has been reported to enhance constitutive and inducible plant defenses against herbivore insects in many species. However, the induction of plant defenses depends on the phytohormone profile induced ...
Effect of UV-B radiation on the contents of UV-B absorbing compounds and photosynthetic parameters in Parmotrema austrosinense from two contrasting habitats
(Wiley Blackwell Publishing, Inc, 2018-09)
We studied the resistance of Parmotrema austrosinense to UV-B stress. We focused on the effects of a high dose UV-B radiation on the content of chlorophylls, carotenoids and UV-B screening compounds. Photosynthetic parameters ...
Effects of solar ultraviolet radiation on terrestrial ecosystems. Patterns, mechanisms, and interactions with climate change
(Royal Society of Chemistry, 2011-02)
Ultraviolet radiation (UV) is a minor fraction of the solar spectrum reaching the ground surface. In this assessment we summarize the results of previous work on the effects of the UV-B component (280-315 nm) on terrestrial ...
Degradation and mineralization of the emerging pharmaceutical pollutant sildenafil by ozone and UV radiation using response surface methodology
(Springer Heidelberg, 2020-11)
Pharmaceuticals and their degradation products which are present in wastewater and superficial waters are becoming an ecological issue. This research investigated the degradation and mineralization of synthetic solutions ...
Water Decolorization Using UV Radiation and Hydrogen Peroxide: A Kinetic Study
(IWA Publishing, 2001-12)
Sometimes, provision of water for domiciliary consumption faces the problem of natural contamination originated by the presence of organic substances such as humic or fulvic acids. Very often, after conventional sanitary ...
The reinforcement of potato cell wall as part of the phosphite-induced tolerance to UV-B radiation
(Springer, 2018-06)
Phosphites (Phis), inorganic salts of phosphorous acid, have shown to be effective in protection of plants against biotic stress. Recently, we have described that potassium phosphite (KPhi) induces tolerance to UV-B radiation ...
Micro-environmental conditions affect grass and shrub seedlingemergence in denuded areas of the arid Patagonian Monte, Argentina
(Elsevier Gmbh, 2015-01)
Harsh micro-environments in bare soil patches generated by disturbance may affect the emergence ofplant species in desert ecosystems. We evaluated the effects of litter addition on the emergence of peren-nial grass and ...
Phenolic composition in grape (Vitis vinifera L. cv. Malbec) ripened with different solar UV-B radiation levels by capillary zone electrophoresis
(American Chemical Society, 2008-04-16)
The responses of Vitis vinifera L. cv. Malbec to different solar ultraviolet-B radiation (UV-B) levels were assessed in two contrasting situations, under sunlight with full UV-B (+UV-B) and filtered UV-B (-UV-B), in three ...
